Answer:
m=(y2-y1)/(x2-x1)
m=(2-0)/(0-(-2))
m=2/(0+2)
m=2/2
m=1 ==> Gradient of graph
x-int: (-2, 0)
y-int: (0, 2)
Explanation:
m=(y2-y1)/(x2-x1)
m=(2-0)/(0-(-2))
m=2/(0+2)
m=2/2
m=1 ==> Gradient of graph
x-int: (-2, 0) ==> When y=0
y-int: (0, 2) ==> When x=0
Answer:
Embryo
Explanation:
Embryo is multicellular diploid body, under mitosis it forms zygote which is single cell. The union of sperm cell and egg cell. This divides rapidly in the days followed by fertilisation. After two week of division it forms zygote. Most of flowering plants in the tissue present in the seed. It is surrounded by the embryo and also provides nutrition in the form of starch, it also have oils and proteins in it.
Another name for unicellular organisms that dominated Earth up to the Precambrian time is prokaryotes. The correct answer is D.
Because their tissue are hypotonic with marine environment Jellyfish are Marine habitat. The solution inside the cell contain fewer solute than outside solution ( marine water) The jellyfish cell losses water through osmosis. In addition these cells gain electrolytes by diffusion.
